Patent GB-1019273-A (GB)
Title: Improved rotary molecular vacuum pump
Inventor: GARNIER HENRI LOUIS
IPC: F04D19/04
Filed: 1962-08-02
Abstract: 1,019,273. Lubricating. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION & COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 2, 1962 [Aug. 4, 1961; Jan. 23, 1962], No. 29691/62. Heading F2A. [Also in Divisions F1 and H2] The end plates 33, 34 of the rotor of a molecular vacuum pump are integral with sleeves 35, 36 which are connected together by a disc 39 carried by the driving shaft 40. Shaft bearings 41, 42 are carried by a drum 43 integral with a frusto-conical base 44 fixed to the casing 5 of the pump by means of a plate 45. The upper bearing 41 is located in or near a transverse plane through the centre of gravity of the pump rotor. A stop 46 comes into play in the event of excessive axial displacement of the shaft 40, e.g. in the event of bearing failure. A lubricating pump 51 of centrifugal type is provided at the end of the shaft 49, drawing in lubricating oil through an axial duct 52 from a reservoir 53 and delivering it through a pipe 54 to the bearings. The oil returns under gravity to the reservoir 53, passing through a space K which is maintained at the pressure of the preliminary vacuum by means of a breather pipe 55. Any oil infiltrating into a space J returns through bores 58 to the space K. Water is circulated through a coil or a jacket 56 to cool the reservoir 53 and thereby reduce the pressure of any oil vapour which may tend to infiltrate into a space H. The inlet and outlet conduits for the cooling water, which extend through the space H, also assist in the cooling of the oil vapour. The space I above the disc 39 communicates with the space J through boles (not shown) but is isolated by the end 38 of the sleeve 35 from the highvacuum space F at the suction end of the vacuum pump. The bearing and the lubricating system are therefore isolated from the high vacuum.

Title: Improvements in or relating to carpenters' chisels
IPC: B25D3/00
Filed: 1945-11-08
Abstract: 602,668. Making chisels. DAVIDSON, P. B. Nov. 8, 1945, No. 29785. [Class 83 (ii)] [Also in Group XXIII] A chisel or gouge is forged from a flat-bar 30 notched at 31 leaving a part 33 to form the tang and necked at 34. The blade is then forged tapered as at 38 and the part 33 extended to form the tang 37 leaving square shoulders 32 from which the sloping blade surfaces 38, 39 extend to the cutting end 40; since no part of the blade lies outside these sloping planes, grinding may be effected on a surface grinder. In a modification, the chisel is formed by dropforging from a round bar resulting in the tapered blade 68, Fig. 21, and tang 70 shouldered at 71.
Patent GB-1476379-A (GB)
Title: Load selective power systems
IPC: H02H3/16
Filed: 1974-07-04
Abstract: 1476379 Protective systems L E BODKIN 4 July 1974 [5 July 1973] 29787/74 Heading H2K In a power supply system a supply circuit comprising an SCR 18 connected between an A.C. source 15 and terminals 21, 22, is arranged to supply power to a load 14 connected across those terminals only if there is connected in series with the load 14, a rectifier 10 arranged to block alternate half cycles of the A.C. supply. This is achieved by connecting a control circuit to the gate of the SCR 18 comprising a capacitor 24 and resistor 25 timing circuit having a time constant greater than one half-period of the A.C. supply and arranged so that if the discharge of the capacitor 24 is prevented on alternate half-cycles by the rectifier in series with the load the capacitor voltage builds up to switch on the SCR so that current is supplied to the load but if there is no such rectifier 10 in series with the load the capacitor discharges on alternate half cycles and the SCR is never switched on because firing potential is never reached. To reduce the effects of possible transient pulses of high magnitude a thermistor 31 is included in series with the SCR in the supply circuit. The rectifier may be a simple diode 10, or an SCR or triac circuit, Fig. 2 not shown. An A.C. equivalent of this power supply system is described where the SCR and control circuit of the supply circuit are duplicated, and two rectifiers are included in the circuit of the load, Fig. 3 not shown. In this A.C. embodiment an RC circuit is incorporated to provide simultaneous cut-off of the two SCRs, and in a further modification slave SCRs are incorporated and monitor circuits are added, Figs. 5 and 6 not shown. A neon indicator lamp and latching circuit may be included.
Patent GB-1273584-A (GB)
Title: Improvements in or relating to programmers
IPC: G05G21/00
Filed: 1969-06-12
Abstract: 1,273,584. Time switches. CROUZET. 12 June, 1969 [13 June, 1968; 4 July, 1968], No. 29975/69. Heading H1N. A programmer for automatic washing machines which comprises a continuously driven reversing cam 2 arranged to step the programme cam drum 6 is provided with means to suppress the stepping action for a manually adjustable time interval to permit extended soak periods, for example. A member 4, pivoted at 26 on cam 2, rides on the circular inner surface 3a of a fixed member 3 and thus holds the pawl 5 (also pivoted on cam 2) out of engagement with teeth 6a on the cam drum 6 until a recess 3b in the surface 3a is encountered, whereupon the pawl 5 is allowed to engage teeth 6a and step the drum 6. However, a part 7b of a bell-crank member 7 is arranged to bridge the recess 3b and prevent this stepping action whilst in the position shown, as determined by a nose 7a riding on a cam disc 6b of drum 6. A time wheel 8 is steadily stepped by a single-tooth 12a on a shaft 12, which is driven with the reversing cam 2, thereby stressing a spring 9 until a projection 8d on wheel 8 cams a nose 7c of bell-crank 7 to lift it (against spring 16) and remove the part 7b from the recess 3b. The subsequent step of drum 6 causes a rise (not shown) on cam 6b to lift nose 7a even further and an extension 7d then lifts a resilient strip 11 acting as a pawl on wheel 8 so that spring 9 restores wheel 8 to its start position determined by projection 8d abutting a stop 13a on a relatively fixed wheel 13. Drum 6 is then stepped for each revolution of cam 2 until cam 6b allows the nose 7a to return to the position shown, whereupon the pawl 11 reasserts itself and wheel 8 is again stepped while stepping of drum 6 is suppressed until projection 8d again cams the nose 7c. The wheel 13 is normally held stationary by a pawl 17 but can be adjusted by a knob 15, via gears 14, 14<SP>1</SP>, so that the position of the stop 13a (and hence the time interval during which stepping of drum 6 is suppressed) may be varied. In modifications (Figs. 2 and 3, not shown) the pawl 11 is omitted and a part (19a) of bell-crank 7 (corresponding to nose 7c of Fig. 1) co-operates with internal ratchet teeth on wheel 8 to act as a pawl as well as a means of lifting part 7b away from recess 3b. In the modification of Fig. 3 (not shown) the tooth 12a driving wheel 8 is synchronized with the position of pawl 5 on cam 2 such that the drum 6 is stepped immediately the part 7b is removed from recess 3b, and the wheel 8 restores immediately tooth 12a moves out of driving engagement therewith.
Patent GB-994162-A (GB)
Title: A process for the production of calcium carbide
Filed: 1962-08-03
Abstract: <PICT:0994162/C1/1> In the production of calcium carbide, a charge which contains calcium oxide and carbonaceous material is preheated to 800 DEG  to 850 DEG  C., in one or more shafts placed adjacent to a closed electric smelting furnace, by means of a current of oxygen-free combustion gas, and the preheated charge is then transferred, without cooling, to the smelting furnace.  The combustion gas may be produced by burning CO-rich gas evolved in the smelting furnace itself during the smelting operation, in combustion chambers connected individually to the shafts.  As shown in the drawing, the charge is preheated in the shaft furnace 5 and then transferred to the smelting furnace, whithout cooling, by pipe 8. Gas generated during smelting, withdrawn through pipe 17, is cleaned and then supplied to combustion chamber 21, in which it is burnt with air from fan 22.  The temperature of the chamber 21 is regulated by passing into the chamber via pipe line 23 a proportion of recycled gas which has already passed through the preheating furnace.
Patent GB-816841-A (GB)
Title: Method for preparing acrylonitrile containing fibres
IPC: D01F6/18
Filed: 1956-10-02
Abstract: In the production of polyacrylonitrile fibres by wet-spinning a polyacrylonitrile solution into an aqueous coagulating bath and stretching the gelled fibres thus formed, the fibres, while they are in aquagel form and in a relaxed free-to-shrink condition, are contacted with an aqueous liquid heat-exchange medium at 90-100 DEG C. for 2-30 seconds and thereafter dried.  The medium has a surface tension of not over 30 dynes per centimetre against air when measured at 90-100 DEG  C. and preferably contains a small proportion of a surface-active agent such as the dioctyl ester of sodium sulphosuccinate.  The polyacrylonitrile may be a homopolymer or an acrylonitrile copolymer containing at least about 85 per cent by weight of acrylonitrile in the polymer molecule.  The aqueous liquid heat-exchange medium is preferably removed from the fibres before they are dried by washing them with a low surface-tension non-aqueous liquid such as acetone. Alternatively, the individual fibres in a tow may be separated from one another by means of an air blast after the tow has been contacted with the heat-exchange medium.  In the example, a solution of polyacrylonitrile in a 60 per cent aqueous solution of zinc chloride is spun into a 43.8 per cent aqueous solution of zinc chloride, and the resulting filaments are washed in distilled water and stretched to a length about 12 times their original length in a water bath at 98 DEG  C.; they are then immersed in a relaxed condition for about 10 seconds in boiling water containing about 0.5 per cent of the dioctyl ester of sodium sulphosuccinate, and dried for about 5 minutes at about 130 DEG  C. The process renders the fibres more thoroughly penetrated by dyestuffs. Specifications 585,367, [Group IV], 716,081 and U.S.A. Specifications 2,558,733, 2,563,640 and 2,614,289 are referred to.

Title: Improved machine for producing shell moulds
IPC: B22C17/10
Filed: 1953-11-04
Abstract: 741,215. Moulding-machines. AKTIE-BOLAGET WESTIN & BACKLUND. Nov. 4, 1953 [Nov. 5, 1952], No. 30474/53. Class 83 (1). A shell-moulding machine comprises two mould - mix containers which are positioned by an inverting device so that application of a preheated pattern or patternunit to one of the containers is effected in one position, while a shell mould is being formed on the pattern or pattern-unit at a second successive position, the inverting device moving the one container and its applied pattern into an inverted position spaced from the initial position and then from the inverted position back to the initial position, a second container and pattern being disposed in the initial position during the time the first container and its pattern are in the second or inverted position, and means being provided for preheating the patterns. Pattern boards 1, which may be shaped as patterns or carry patterns, are supported downwardlyfacing on frames or carriages 3 having stripping bolts 4. The carriages 3 are slidable on rails 8, 20 and may pass through the stages A-H of the apparatus under the action of reciprocating rods 9, 19. At A the pattern unit is introduced into the apparatus and moves to B where parting liquid is sprayed on to the pattern from a container 10 moved upwardly by a ram 11. At C the unit enters a preheating electric furnace 12 and at D is applied to one of two mould-mix containers 14, which are supported on a frame 30 on a rotatable shaft 31. Each container is associated with a cylinder 33 having a piston 39 connected to and actuating a frame 40 supporting the rails 8 so that these may be moved vertically to clamp the pattern unit against the container 14. The shaft 31 is then rotated through 180 degrees so that mix falls on the pattern while the other container, with a previously formed pattern and support clamped thereto, occupies the upright position. The pattern and support then moves to station E where it is raised by lifting equipment 15 to the upper rails 20. At F the assembly passes through a curing furnace 21 and at G a piston 25 moves it downwardly until the pattern board 1 engages stops 26, continued movement of the piston causing the mould to be stripped from the pattern and fall on to a conveyer 27. Thereafter the pattern unit is again elevated and placed on the rails 20, transferred to station H and lowered to the starting position A. At either position H or A, the cleaning and reconditioning'of the pattern-unit takes place. In a modification, the pattern-units are traversed manually, and in a further modification, Fig. 6, they move through the treatment stages in a circular path, fed by an arm 67, or the table 66 may rotate.

Title: Fungicidal and bactericidal agents and methods of preparing the same
IPC: C07F3/14
Filed: 1953-11-06
Abstract: The invention comprises organo-mercuric salts of hydroxyquinoline having an ionic bond linking the organic mercury radical to the oxygen atom of the hydroxyquinoline.  The organic mercury radical may be a substituted or unsubstituted alkyl, cycloalkyl or aryl mercuric radical.  5-, 6-, 7- and 8-hydroxyquinolines, substituted by halogen atoms, nitro or alkyl groups may be utilised.  The compounds of the invention may be prepared by reacting an alkyl- or aryl-mercuric compound, particularly the hydroxide or acetate, with the hydroxyquinoline in solution, suspension, by fusion or by mixing in the solid state (e.g. dry grinding).  Heat may be applied if desired. These compounds have fungicidal and bactericidal properties.  In an example 8-hydroxyquinoline is fused with phenyl mercuric acetate, the mass dissolved in benzene and the so formed solution crystallized by concentration.  The product, 8-phenylmercuric - hydroxyquinoline may be recrystallized from alcohol.  In a further example (8) (as overleaf) other examples describe the preparation of 5-chloro-8-phenyl mercuric-hydroxyquinoline, 5-chloro-7-bromo-8 - phenylmercuric - hydroxyquinoline, 4-chloro - 8 - phenylmercuric - hydroxyquinoline, 2 - hydroxynaphthyl - 1 - mercuric - 8 - hydroxyquinoline, and cetyl-mercuric-8-hydroxyquinoline.  In a further example (8) 8-hydroxyquinoline is reacted with 2-acetoxy-mercuric-p-cymene in solution in methyl alcohol.
